Bifocal Lenses

What are Bifocals?

Sometimes our vision fails us at two or even three distinct distances, especially as we age. Bifocal lenses—lenses with two distinct viewing areas—have traditionally been a reliable solution to such a dilemma. (A lens with three distinct viewing areas is called a trifocal.)
 
By distinct, we mean there are noticeable lines separating the two different fields of vision within a bifocal lens surface. A slight adjustment to the angle of the head allows wearers to choose which lens area to look through based on the distance of the object they’re trying to see.
 
A farsighted person who also has trouble reading may be prescribed a pair of bifocal reading glasses, for example. The upper section of the lens would correct difficulties seeing objects at distance, and the lower section would assist in reading. (Bifocal glasses date back to the days of Benjamin Franklin!)
 
While wearers quickly adjust to the line separating the multiple vision fields, it is a noticeable distraction within the lens itself. This line can be eliminated using a newer lens technology called progressive lenses.
 
Progressive lenses incorporate two, three, or more fields of vision within a single lens without noticeable lens lines. Bifocal, trifocal and progressive lenses are all considered “multi-focal” lenses—lenses that provide correction to multiple vision problems.

A Message to Our Patients

TSO Woodlands will continue to follow health and safety guidelines recommended by the CDC by requiring all patients and staff to continue wearing a mask when entering our office for any service. As a healthcare provider we want to ensure the safety of all of our patients and staff. If you arrive without a mask for your appointment, we will be happy to provide one for you.

We understand there are strong feelings on the mask debate and thank you for your cooperation, understanding, and patience as we navigate this challenging time. We look forward to seeing our patients back in the clinic again and strive to provide excellence in eye care while maintaining your health and safety as our highest priority.

Warmest Regards,
Dr. Young and TSO Woodlands Staff
